Well, even though folks like you and me keep getting told that we're wrong, more and more numismatists who make their living buying, selling, grading, and writing about coins - agree with us
Great coins but no fun to grade I like grading coins in hand. It can be a fun game. However, I find grading inverse relief Indian gold coins to be like punishment. They are no fun at all .
